1. We were not propagating selectedness updates from option to select if the option was inside an optgroup. 2. When two or more options were selected, we were always favoring the last one in tree order, instead of the last one that got checked. 3. We were neglecting to return in the `display size is 1` case when all elements were disabled. This was covered by some of the :has() selector tests. :^)
